' NQN-REFILLAIBLE BOTTLE.

tion being to provide simple, reliable and et ficient means for indicating initially that no portion of the contents of thebottle has been dischargech. and't'or indicating thereafter that a portion of the contents of the bottle has been discharged, ,thus guarding the intending purchaser of a bottle of liquid against thepurchase of a bottle of liquid which has been partially or wholly emptied of its original contents and refilled.

A further object of the invention to provide a novel type of valve mechanism for the purpose described, which will serve as an initial closure to prevent escape of the contents of the bottle, and which maybe adjusted to permit of the discharge oft-he contents of the bottle and which will then serve as means for indicating that the bottle has been initially filled and opened.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanymg drawing, in which Figure 1 1s a vert cal longltudinal sec tion through the neck of a bottle embodying my invention. showing the valve or stopper in normal position and serving as a seal.

Fig. 2 is a. view similar to Fig. 1 showing the valve or stopper in the process of being forced downward from a scaling to an indicating position.

Fig. 3 is a horizontal transverse section on the line 33 of Fig. 1.

Fig. 4 is a horizontal transverse section on the line t-et of Fig. 2.

, Referring to the drawing, 1 designates the body ot a bottle having an abbreviated 'or shortened neck portion .2 formed with a reduced extension 3. The neck portion 2 is designed to be completed by the application of a primarily independent cap 1, preferably made. like the bottle, of glass or other suitable transparent or translucent material. This cap 4 is provided with a top wall 5 having a constricted o, .-ening 6 therein,

and said cap portion fits at its lower end about the reduced extension 3 and is adapted to be secured thereto in any suit able manner. In the present instance I have shown the extension 3 and cap portion formed with grooves in their meeting faces to receive a filler 7 of cement or other suitable n' atcrial, whereby the cap is secured in place and can not be removed without either breaking or otherwise mutilating the bottle or cap in such a manner as to indicate that the bottle has been tamperedwith.

The cap 4 servesas an inclosing casing for an interiorvalve shell 8, also preferably madeof glass or other suitable transparent or translucent material. This valve shell snugly fits the interior of the cap and is in the form of a tapered tube provided be tween its center and upper end with an interior annular shoulder J forming a passage 10 and sub-dividing the interior of said shell into an upper scaling chamber 11 and a lower runway or receiving chamber 12, said chambers being in communication through the passage 10.

Inter-posed between the lower edge of the shell and .the upper edge of the neck portion 3 is a *asher or gasket 13 provided with an opening 11, and interposed between the upper edge of the shell and the wall 5 of the outflow oi. the liquid when the bottle is in condition for the liquid to be discharged. In practice, the opening 16 is preferably made of the same size as the opening 6, and the washers 13 and 15 are made of cork or other suitable elastic material and serve to hold or bind the valve shell in position against movement and to also seal the interior joints against the leakage of liquid.

A valve or stopper 17, preferably of the ball type, is provided for initially scaling the bottle and to serve as an indicator after the bottle is initially unsealed. This valve or stopper is designed to be initially placed in the chamber 11 to seal the openings 6 and 16 against the escape of the contents ot" the passage and opening 16 to seal the bottle against the discharge of liquid, in which position the stopper also indicates the fact that the bottle has been filled but once and that no portion of its contents has as yet been discharged. In order to break this seal, a form of tool is provided consisting of a stem 19 having a handle 20, which stem is inserted through the ppenings 6 and 16 and arranged to bear against the stopper 17, which, by the application of proper pres sure, is forced downward through the ring 18 into the chamber 12, the ring 18 expanding to allow the stopper to pass and-then contracting to prevent its return to the chamber 11. The bottle will then be unsealed for the discharge of its contents as desired, in which operation the stopper 17 will roll back and forth in the chamber 12, being limited in outward movement by contact with the shoulder 9, so that by tilting or canting the bottle "he liquid may be discharged. The chamt- 12 is of sulhciently larger diameter than the stopper 1'! to per-. mit the liquid to freely flow past the same, but if desired said chamber may be provided with a series of longitudinal grooves 21 to allow the liquid to run'freely past the stopper in any position of the latter. When the bottle is disposed in a vertical position,

the stopper 17 rests upon the, bottom Washer 13 and may close the opening 14, but if de' sired any\ s'uitable form of stopper may be inserted in the openings 6 and 16 to close the bottle against the access of dust, dirt and other foreign substances.

It will thus be understood that after the bottle has been filled the stopper 17 will act as a closure, but that when this closure is once depressed into the chamber 12 it can not return to its normal sealing position, and therefore the contents of the bottle may be as freely discharged as desired. As, however, the stopper will remain in the chamber.12, it will indicate to anyone familiar with the type of bottle that the bottle has been initially unsealed, thus warning the intending purchaser of a bottle of liquid of that fact, thus safe-guarding the public against the purchase of a bottle which has been refilled with liquid or from which a portion of the original contents has been drawn.

It will be observed that the shoulder 9 is provided with a downwardly and inwardly inclined uppei surface or seat for the elastic ring 18, and that the said ring 18 is of circular form in cross section. By this construction of the shoulder and the ring any possible displacement of the ring in a downward direction is avoided, while the inclined face of the shoulder permits the ring to spread vertically under downward forcing pressure of the valve 17, in which action the cross sectional contour of the ring, as shown in Fig. 2, various from circular to oval or elliptical form, the sides of the ring thus being lengthened in a vertical direction as the ring spreads. Hence, while the valve will be normally supported by the ring in a tight sealing condition against the ingress of dust, dirt or other foreign substances, pressure upon the ring of a certain degree will permit the valve to be forced downwardly into the runway 12, the elastic ring thereafter contracting and resuming its norchanges involving claims may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having thus fully described my invention,

I claim 2-- 1. A bottle having a fluid discharge passage, including superposed chambers connected by a constricted passage, said .passage defining an annular shoulder having an upper surface inclined downwardly and inwardly toward said passage, the said upper chamber communicating with the final outlet and the lower chamber with the interior of the bottle, an inelastic vertical stopper disposed within the upper chamber to seal said constricted passage and the final outlet, and an elastic ring of circular form in cross section resting upon the inclined upper face of the shoulder, said ring forming a seat' for normally holding said stopper in sealing position, said ring adapted to be expanded from a cross sectional circular to a cross sectional elliptical form under pres sure upon the stopper, whereby said stopper maybe freely forced downwardly through the ring and constricted passage into the lower chamber.

'2. A bottle having a shortened neck portion, a cap permanently secured thereto and provided with a final outlet, a valve shell inclosed by the cap and provided with an interior shoulder forming upper and lower chambers and a constricted intervening passage, said shoulder having a downwardly and inwardly inclined upper surface, the

lower chamber, and means for upper chamber communicating with said final outlet and the lower chamber with the bottle neck, an elastic ring cross-sectionally of circular form confined within the upper chamber above said constricted passage and resting upon the inclined upper face of said shoulder, an inelastic spherical stopper adapted to be disposed in the upper chamher and held by the elastic ring in position to close the final outlet, and adapted to be forced downward through said ring into the holding the valve shell in position within the cap.

3. A bottle having a shortened neck portion, a cap permanently secured thereto and provided with a final outlet, a valve shell inclosed by the cap and provided with an interior shoulder forming upper and lower chambers and a constricted intervening passage, the upper chamber communicating with said final outlet and the lower chamber with the bottle neck, an elastic ring confined within the upper chamber above said constricted passage, a spherical stopper adapted to be disposed in the upper chamber and held by the elastic ring in position to close the final outlet, and adapted to be forced downward through said ring into the lower chamber, and elastic washers disposed between the lower edge of the shell and the edge of the neck and between the upper edge of the shell and crown wall of the cap, respectively.-

In testimony whereof I atii my Signature.
